Subject: [PATCH] make Linux configuration crosscompile aware

Currently, the "Linux" configuration cannot be cross compiled because
the compiler is configured unconditionally. We add the CROSS_COMPILE
prefix: this way it is easily possible to overwrite that variable from
the commandline and use any cross compiler.
